The Fiocchi Field Dynamics Performance 22 WMR 40gr FMJ ammunition delivers reliable rimfire performance for hunters, plinkers, and trainers who want consistent, affordable rounds without compromise. Loaded with 40-grain full metal jacket projectiles and brass casings, this 22 Magnum ammunition combines the proven reliability of Fiocchi's manufacturing with the value shooters expect from field-grade ammo. Whether you're zeroing a new rifle, running practice drills, or taking small game at moderate range, these rounds give you the ballistic consistency and noncorrosive primers that let you focus on shooting rather than cleaning.
Each box contains 50 rounds of new production ammunition, so you can stock up and spend more time at the range without sticker shock. The full metal jacket construction provides consistent velocity and trajectory, while brass casings make them reloadable for shooters who handload. Fiocchi's European heritage and quality control mean you're getting ammunition that fires reliably, shot after shot, across a wide variety of 22 WMR rifles and carbines.
If you run a rimfire for hunting, sport shooting, or tactical training, 22 WMR offers more power and flatter trajectory than standard 22 Long Rifle while staying affordable enough to practice with confidence. Fiocchi Field Dynamics delivers that sweet spot between cost and performance.
